An evaluation of the Public Health Grid (PHGrid) technology during the 2009 H1N1 influenza pandemic could enhance the capabilities of epidemiologists and disease-control agencies when the next emergent disease appears, according to a study published in the International Journal of Grid and Utility Computing. http://medicalxpress.com/news/2011-06-grid-approach-pandemic-disease.html Diseases, Conditions, Syndromes Wed, 15 Jun 2011 09:34:37 EST news227349262 (Medical Xpress) -- A team of Melbourne scientists has discovered a new type of cell in the immune system. Their findings could ultimately lead to the development of novel drugs that strengthen the immune response against particular types of infectious organisms. http://medicalxpress.com/news/2011-06-cell.html Medical research Tue, 14 Jun 2011 10:05:28 EST news227264697 Chronic myeloid leukemia (CML) is a particular form of leukemia or cancer of the bone marrow, which can be treated with targeted imatinib. However, in some cases this medicine has no effect. Researchers at the VIB Vesalius Research Centre, K.U. Leuven, under the direction of Peter Carmeliet, have investigated the role of placental growth factor (PlGF) in mice with CML. Blocking this growth factor increases the life expectancy of these mice, even in those resistant to imatinib. http://medicalxpress.com/news/2011-06-efficient-therapy-specific-leukemia.html Cancer Tue, 14 Jun 2011 10:01:28 EST news227264422 Researchers from Harvard Medical School and MIT have developed a new approach for identifying the "self" proteins targeted in autoimmune diseases such as multiple sclerosis, diabetes and rheumatoid arthritis. http://medicalxpress.com/news/2011-06-approach-autoimmune-diseases.html Medical research Thu, 02 Jun 2011 11:20:04 EST news226230343 Increased transportation of live pigs appears to have driven an increase in the diversity of swine influenza viruses found in the animals in Hong Kong over the last three decades, according to a new study. http://medicalxpress.com/news/2011-05-long-term-swine-flu-viruses-viral.html Diseases, Conditions, Syndromes Wed, 25 May 2011 13:00:15 EST news225546399 Oncolytic viruses quickly infect and kill cancer stem cells, which may provide a treatment for tumors that are resistant to conventional chemotherapy and radiation, particularly pancreatic cancer, according to new research from Memorial Sloan-Kettering Cancer Center in New York. The findings are especially important since pancreatic cancer has a poor prognosis and is difficult to detect and treat at early stages. http://medicalxpress.com/news/2011-05-oncolytic-viruses-effectively-pancreatic-cancer.html Cancer Mon, 09 May 2011 11:36:12 EST news224159739
